I Application filed May 3,1928. Serial No. 166,156.

My present invention has reference to grain or similar cars, and myprimary object is a particular construction andmounts for inside doorsof such cars, whereby the doors may be readily moved to. an out of theway position in aear and secured there when the car is empty, andreadily returned and efiectively locked to the door openings when thecar is to be filled.

A further object is to provide a box or grain car with inside tracksofrpa rticular and peculiar formation, the rails of each track beingengaged by rollers on the posts or hanger members for the doors, so thatthe doors, after they are unlocked, may be raised on their hangers andmoved bodily therewith to the other end of the rails which terminate atthe center of the ends of the car, at which points the doors maybelowered and secured to the said car ends, so

that the doors will be sustained in an unobstructing position when thecar is empty, and further wherein, when the doors are in normal carclosing position they will be effectively, locked on the car toestablish a grain tight closure therefor.

A further ob'ect is the provision of a device for this purpose which maybe readily installed in different classes of box cars, and

which, while of an extremely simple construction, will be foundthoroughly effective for its purposes.

lVith the abovebroadly statedobjects in view, the improvement furtherresides in certain other novel features of construction,

' combination and operative association of parts, my preferredembodiment of which is illustrated by the accompanyingthree sheets ofdrawings in which:

Figure 1 is a central vertical and longitudinal sectional view through asufficient portion of a box or grain car to illustrate the applicationof my improvement;

Figure 2 is a horizontal sectional view approximately on the line 2-2 ofFigure 1; Figure Bis a transverse sectional view showing the doorlatched against one'end ofthe car;

Figure 4 is a fragmentary side elevation, as seen from the outside; andi r "Figure 5 is a detail elevation of the upper 7 portion of one of thehangers, the rail being in section.

distinction by thenumeral 3, and each of these posts is bored to providespaced sockets V 4-; for the reception of bolts that are slidably,mounted through brackets 6 that are fixed on theouter side of the doors7.

,On each bracket plat-e6 there is pivotally secured a cam member 8designed to engage with thehandle portion 9 ofeach bolt when the boltsare thrown home. f

Each door 7 has on its ends facing out wardly the vertically, extendingcleats 10% the outer edges of which engage the inner edges 'of the sidesof the door opening 2 to make a grain tight joint, and on the' outerface of each door thereis securedan elongatedmetallic supporting member11 having the flanged ends 12. The brackets 6iare secured on thecleats10 and on extensions 10 thereof, which might be separate bloc-ks;

A rod l3'extends through suitable openings in the flangeslgof themembers 11, and for conveniencel will hereinafter refer to the said rods13 as hangers for the doors 7 The lower end of eachThanger may be jFixedlysecured by any suitable means to, or adjacent to, the topofthecar 1 there are oppositely directed rails 18(1Each' rail preferablyhas the cross-section of an ,I-beam;

that is, each side. ofr'the' rail is grooved.

throughout itslength. "Each Trail includes a straight portion 19arranged substantially parallel with and (close to the respectivesidesjof the car. 1 From the straight portions 19 'tlierails are curved,preferably in an ogee curve, as at 20, and from thence are extended in astraight portion, as at 21, tothe respecrails, terminate ina plane witha vertical [T'By reference to FigureQ of the drawings it will be noted,that the respeetive} ends' o'f 'tive ends of the car. Thefportions 21 ofthe I the rails 18 have depressions therein, as at 22 and 23). Thedepressed portions 22 are disposed in a line with a vertical center ofthe door openings 2, and of course, the depressed portions 23 aredisposed at the ends of the ear. The rollers 17 are designed tor. travelon the lower flanges of the rails 18' and are out of contact with thewebs of the said rails.

lVhen the doors 7 close the doorways 2 the rollers on the hangers 13will be received in the depressions 22, which allow the said doors torest on the floor of the car, on each hanger 13 there is secured aflexible element which is preferably in the nature of a chain 24, whileon the upper edge of each door 7 a hook 25 is pivoted. When the bolts 5are thrown to' unlocking position the door 7 is-raised on its hanger andis held out of car floor contacting engagement by bringing the hook25into one of the links of the chain 241 The door may be now bodily movedwith the hanger on the track 18, and after travelingoverthe curvedportion 20 of the said track, the door is swung on its hanger to bringthe said door transversely of the car. The door is further moved on thetrack until the said door contacts the end of the car. The hanger withthe door rollers will move downwardly as the rollers are received in thedepressions 23, and the ends of the car have pivotally mounted thereonangular latch members 26 which are swung to engage with and .hold thedoor from movement. hen the doors are thus positioned no obstruetion isoffered to the loading or the emptying of the car if used for othermaterials not requiring the use of grain doors. lVlienthe doors arebrought to elose the openings 2 a perfect grain tight joint between thedoors and the car is eiTectiv ely provided, and incident to the latchingof the doors in either their opener closed positions accidental movementofthe said doors is positively, prevented. a

While I have shown and described my invention as embodied in the formwhich I at present consider best adapted to carryout its purpose; itwill be understood that it capable of modifications andthat I do not.desire to be limited in the int srprctation ot the following claimsexcept as here necessitated by the. state of the prior art. l V hat Iclaim as my invention a ud'desire to securehy Letters Patent is lf'l hecon'ibination of a grain car or the like having door openings inthesides thereof. inside doors for closing said openings. and means forlocking the doors in cloed position, ofa double-flangedover head trackhaving a portion disposed over each door and from thence curved towardand terminating at the centerof the ends, ahaii'ge hay ng a b furcatedupper end, rollers' ournaled therein and disposed on flanges of thetracks, means swingably connecting each hanger to each door, and meansfor holding the doors raised on the hangers.
